Ditto. That's what mine does.
I am having an issue getting it to discharge the battery. It worked before. When I put it into “self consumption” it does nothing. The status is “bat grid”, “grid”, “charge” (DC/DC). I am also getting a breaker trip when I am at work but not seeing any alarms other than a disconnect from grid. After it happens.
My inverter has been not acting as expected. I haven't been able to pull any power from the battery to feed loads. Last night it made a sizzling noise, lights flickered, then a big pop. I expect to blew-up something inside. Its within the 30 day return policy. I think its time for a different option.

Yikes! I would say so.
Warranty?

Within the 30 day return policy I can't say I blame him for opting to return and get something different. Not that we can be sure it was the fault of the inverter and not something relating to the installation. None of us are there looking at it.
It should also have a 5yr warranty enforced by Watts.Within the 30 day return policy I can't say I blame him for opting to return and get something different. Not that we can be sure it was the fault of the inverter and not something relating to the installation. None of us are there looking at it.
Scenario ... The nhx resides in the shop. The poco's meter is 50' away between the shop and house. The house is ~100' on the far side of the meter. No net metering agreement.
Could I place the cts' on the nhx's grid connection, set it to something low like 500w export to grid, and have it export some of the excess power to the house without it going to grid? The house should always be pulling considerably more than 500w.

Any type of grid tie type merging with limiting will work until it doesn't. There are no guarantees you won't have some feedback onto the grid. If you are absolutely certain you always have 500watts of steady consumption, then you can *maybe* do it. If any of that ever dips down though, the inverter will not react fast enough to avoid exporting onto the grid. The wattage it is offsetting has to be 100% of the time, no exceptions.
Watch out for power outages and such, your inverter might come back on and start exporting faster than you can turn your loads back on.
Yes, within the 30 day return option too
Gotta know, was it a hassle free return? Was Watts easy to work with?
The version I got wasn’t the watts247. Mine is sunpower gold version. So far they asked a few questions but haven’t authorized a return yet. But I am getting it ready to ship. If I get a full refund. I am looking at the 12kw model. If I can’t find a better deal. Then I will get it from watts247. They are only about an hour or so away. I would just drive down there and get it. I have bought panels and solar assistant orange pi from them.

Good luck with SGP, be firm with them right away and accept no BS.
1 hour from watts247 is your obvious option.

Thanks for the feedback. I am hopeful getting a full refund. I got a crazy good deal on it, being a returned unit that I purchased. But I am right at my 30 return option.

I was in a similar position. My last inverter was an SGP ip6048. It took about 3 months for them to get the part to fix the inverter. They're the reason I went with watts247 for the current one because there's someone within driving distance that I can yell at if this thing breaks.
I am not sure where that information came from, because their webpage clearly states less than 75W Idle consumption per unit

Looking for advice for my situation. I am currently in a rental type situation that I can't really add solar to the house, but I am buddies with the owner so I can mess with electrical stuff. I have two electric cars and am looking to save money on electricity and have a more robust battery backup situation for storms etc. We just went 11 days with no power thanks to Helene. I have a ioniq 5 that does 15a 120v V2L, but I would like more than the 1800w during outages.
Anyway my thought is to move to a Time of Use energy contract. And to get a NHX10 along with a 7 to 14kwh battery to run most of my homes energy during peak hours (3 hours everyday) and recharge during off peak times. I think when adding in my electric car charging in off peak I could save at least 35% of my electric bills. (plus hopefully get the 30% tax credit) During extended outages my thought is to use the V2L from the car's ~60kwh useable battery (granted at 1800w) as a generator input to supplement my smaller house battery.
Would the NXH10 accomplish this well, or is it just dumb to try and do this without solar?
Specifically I am curious on two things:
1. Would generator input work as I believe it would? Would it help offset loads or just charge the battery? Can it take in AC while still running full inverter loads?
2. For my use case would I need to create a new panel with critical loads or can I just feed into my current panel and do a "zero export" option?
Thanks

Why not keep the inverter totally off grid with a sizeable battery bank? Not sure how much electricity you consume in the EV, but one nhx charging a 120kwh bank with 18k of solar should get you around the block a time or two. If the grid goes down, you could manually, or automatically, if so inclined, feed some of that back to the house.
1) Don't have a genny so I cannot confirm if the genny will go to loads, battery, or both. If it goes to battery you will loose a little power in the conversion, but it's still there to use. The thing has a lot of options and I'm not good with pushing buttons on computer stuff and getting it to behave. Take in ac ... from the grid, or ac coupled to solar panels? It outputs 10k or ~45amps. The wiring isn't large enough to support more than that except maybe for a short burst to get a motor started.
2) Depends. NEC is very particular.
